-
electromyogram
(EMG) - neurodiagnostic graphic record of electrical activity of muscle at rest and during contraction to diagnose neuromusculoskeletal disorder
-
magnetic resonance imaging
(MRI) - nonionizing imaging technique using magnetic fields and radiofrequency waves to visualize anatomical structures
-
nuclear medicine
radionuclide organ imaging - ionizing imaging technique using radioactive isotopes
- bone scan
- radionuclide image of bone tissue to detect tumor, malignancy, etc
-
radiography
(x-ray) -
x-ray imaging;
an ionizing technique commonly used in orthopedics to visualize the extremities, ribs, back, shoulders, joints, etc - arthrogram
- x-ray of joint taken after injection of a contrast medium
- diskogram
- x-ray of an intervertebral disk after injection of a contrast medium
-
dual-energy x-ray absorptiometery
(DEXA) - x-ray scan that measures bone mineral density of spine and extremities to diagnose osteoporosis, determine fracture risk, and monitor treatment
-
computed tomorgraphy
(CT)
computed axial tomorgraphy
(CAT) - specialized x-ray procedure producing a series of cross-sectional images that are processed by a computer into a 2-dimensional or 3-dimensional image
- sonography
-
ultrasound imaging;
nonionizing technique useful in orthopedics to visualise muscles, ligaments, displacements, and dislocations or to guide a therapeutic intervention such as that performed during arthroscopy
